Some articles on inertia matrix, inertia:
... The moment of inertia matrix in body-frame coordinates is a quadratic form that defines a surface in the body called the inertia ellipsoid ... Let be the inertia matrix relative to the center of mass aligned with the principal axes, then the surface or defines an ellipsoid in the body frame ... vector, then from the definition of the inertia matrix, where In is the moment of inertia of the body around the axis in the direction n ...
... The use of the inertia matrix in Newton's second law assumes its components are computed relative to axes parallel to the inertial frame and not relative to a body-fixed ... that as the body moves the components of the inertia matrix change with time ... In contrast, the components of the inertia matrix measured in a body-fixed frame are constant ...
Famous quotes containing the words matrix and/or inertia:
“The matrix is God?
In a manner of speaking, although it would be more accurate ... to say that the matrix has a God, since this beings omniscience and omnipotence are assumed to be limited to the matrix.
If it has limits, it isnt omnipotent.
Exactly.... Cyberspace exists, insofar as it can be said to exist, by virtue of human agency.”
—William Gibson (b. 1948)
“What is wrong with priests and popes is that instead of being apostles and saints, they are nothing but empirics who say I know instead of I am learning, and pray for credulity and inertia as wise men pray for scepticism and activity.”
